“…The main function of scintillator is to convert rays to visible light, and its optical conversion performance is a key factor affecting the performance of indirect semiconductor detectors. Table 1 lists the properties of commonly used scintillator materials [17] . In practical applications, the type of scintillator is generally determined according to the type of ray and parameters required to be detected, and then the matching photodiode is determined according to the characteristics of the scintillator, and the photodiode is usually a Si-PIN diode.…”

Aiming at the problem of dose measurement inaccuracy due to the large volume of ionization chamber in gamma knife small field measurement, a micro-volume semiconductor detector for gamma knife dose measurement was developed. The semiconductor detector was designed with six semiconductor detectors attached to a ceramic cylinder, thus avoiding the measurement directivity defect caused by the placement of a single semiconductor detector. At the same time, it also improves the sensitivity of the entire semiconductor detector. The experimental data show that the developed gamma knife semiconductor detector has the characteristics of good angular response, high sensitivity and good stability. The output dose of gamma knife in each field is measured with the developed semiconductor detector, then the calculated field output factor is consistent with the manufacturer's factor, so the developed semiconductor detector is suitable for measuring the output dose in small field.

Copper-based halide perovskites have been considered as promising scintillators. However, they still cannot meet the requirement of low-dose-rate X-ray imaging in medical diagnosis. Herein, we design a fiber optic plate (FOP) coupled perovskite X-ray camera to reduce the dose rate toward dental X-ray imaging. Tl doped Cs 3 Cu 2 I 5 prepared via molten salt reaction has a high light yield of 72,000 photons/MeV, resulting from Tl 1 0
